Tungsten Needle
Tungsten needles are normally divided into pure tungsten needle, rare earth needle, and doped tungsten needle. It is mainly used for the high-intensity gas discharge electric arc tube. The surface can be supplied in a shiny or matte; dependent upon thickness and width parameters.
Tungsten needles are suitable for TIG welding and other electrode materials because of its characteristics。

Application
Tungsten needles are suitable for TIG welding and other electrode materials because of their characteristics
The addition of rare earth oxides to the metal tungsten stimulates its electron work function, making the tungsten electrode welding performance can be improved: the arc of the arc has better performance, better stability of the arc column, and the electrode burn rate is smaller. Conventional rare earth additives are cerium oxide, lanthanum oxide, zirconium oxide, yttrium oxide, and thorium oxide.
Tungsten needle for TIG welding, which is in the tungsten matrix by powder metallurgy method of incorporation of about 0.3% -5% of rare earth elements such as cerium, thorium, lanthanum, zirconium, yttrium and so on the production of tungsten alloy bar, Pressure from 0.25 to 6.4 mm, the standard length from 75 to 600, and the most commonly used specifications for the diameter of 1.0,1.6,2.4 and 3.2, the shape of the electrode side of the TIG is an important factor, when When using DCSP, the electrode ends must be ground to stabilize the arc. When welding with AC power, do not have to wear the electrode.
Specification
All diameters above 1.0mm could be provided.
